JOHN SIMPSOX, OF CLEVELAND, OHIO, ASSIGNOR- 'TO THE CLEVELAND MALLEABLE IRON COMPANY, OF SAME- PLACE.

SCYTH E-SNATH.

SPECIFICATION forming part of Letters Patent No. 389388, dated April 6, 1886.

Application filed May 1%, 1885. Serial No. 165,680.

To all whom it may concern.-

Be it known that I, JOHN SIMPSON, of Cleveland, in the county of Cuyahoga, and State of Ohio, have invented certain new and useful Improvements in Scythe-Snaths; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, malting part of this application.

Myinvention relates to certain new and useful improvements in scythe-snath fastenings, and has for its main objects the production of a fastener which shall permit of the usual adjustments of the scythe, and which at the same time shall require no other bolt in the structure than that which is always employed at the lower end of the snath to hold the tang of the scythe thereon, thus simplifying and cheapening the structure; and to these main ends and objects my invention consists in certain novel features of construction,which will be hereinafter more fully described, and par ticularly pointed out in the claims following the general description.

In the accompanying drawings, Figure l is a plan of the under side of the lower end of a scytho-snath having my invention applied thereto, and showing also a portion of a scythe held to the snath by my novel means. Fig. 2 is a side view thereof. Fig. 3 is a longitudinal vertical section of the same, taken at the line as :0 of Fig. 1. Fig. 4 is a plan View of the under side of the swinging shoe-piece or socket seen at Figs. 1, 2, and 3; and Fig. 5 is a vertical longitudinal section of a modification of the shoepiece seen in the foregoing figures.

In the several figures the same parts will be found designated by the same letters of reference.

A is the scythe, provided, as usuahwith the tang a, and craw or claw a, bent downwardly and at right angles to the tang.

At the lower extremity of the snath will be found the usual ferrule or band, B, and eyebolt or clampingloop C, threaded at its upper end, and the usual nut, c, for drawing down the bolt C and securing the tang of the scythe to the snath. By preference I form integrally with the ferrule B a face-plate, B, which I fasten by a screw to the slabbed or (No model.)

flattened portion of the lower end of the snath D, and ,said face-plate is preferably formed at each side with a wing or car, 12, that extends down a little way on each side of the snath, so as to give a firm hold for the parts. The said face-plate, as will be seen, is formed with a curved transverse slot or opening at F, and at each side of this slot are formed serra tions i, that radiate from a point situated at about the center of the eyebolt.

E is a sliding socket or shoe-piece, that is formed or provided with a hole at e, for the reception of the claw a of the scythe, and said socket. as seen particularly at Fig. 4, is formed on its under side with radially-arranged serrations or teeth corresponding with those made in the face-plate B.

The socket shown at Figs. 1, 2, 3, and 4 is cast, as shown, with projecting ribs or webs e e, from each of which project pins or teats e, for a purpose that will be presently explained. At f the wood of the snath is cut out or removed to accommodate the ribs 0 of the sliding socket, and also a plate-like de vice, a which is secured to the ribs of the socket-piece by means of the little lugs or teats a which pass through holes or slots in the said plate and are riveted thereupon.

From an inspection of Fig. 3 of the drawings it will be seen that the plate 6 is longer than the width of the curved slot formed in the face-plate B, and the socket-like device thus always held in working position relatively to the slot in the face-plate, and prevented from ever becoming detached. It will be understood of course that the plate e is riveted in place after the ribs have been passed through the slot in the face-plate and before the face-plate is screwed onto the snath.

In order that the sliding socket may be disengaged from one set of the teeth on the faceplate and moved to some other position within the slot, and there engaged with another series of the teeth, it will be understood that the distance between the inner surface of the face plate and the outer surface of the device 6 should be, as shown, slightly in excess of the depth of the teeth of the socket.

In the modification shown at Fig. 5 the socket is made of malleable iron with the feetlike portions 6 depending in straight lines, as

indicated by the dotted lines; and in assembling the parts together these feet or lugs are bent outwardly at about right angles, to form stops to serve the same purpose as the plate 6 (Shown at Fig. 3.)

From what has already been said, the construction of a contrivance embodying my invention will be readily understood, and the following description of the mode of operation of the same will enable any one skilled in the art to which my invention appertains to use a scythe-snath fastening embodying the same. Supposing the scythe to be detached from the contrivance entirely, the eyebolt G lying loosely within the snath, and the sliding socket in about the position shown at Fig. 1, and it be desired to secure the scythe in place upon the snath, its tang a is passed through the eyebolt G and its claw permitted to drop into the hole in the sliding socket. The nut c is then screwed toward the ferrule, thereby drawing up the eyebolt, and thus clamping the root of the tang securely between the ferrule and the inner surface of the eyebolt, at the same time, through the intervention of the claw end of the tang, drawing into engagement the teeth and the spaces between the teeth of the socket with the teeth and the spaces between the teeth of so much of the face-plate as is covered by the socket, thus securely holding all the movable parts together. If it be desired now, as is often the case, to vary the hang of the scythe to throw itspoint either in or out, the nut c is loosened sufficiently to permit the disengagement of the teeth on the socket and face-plate; and the socket, with the claw still within the hole, is moved either to the right or left, the tang vibrating from a center at about the center of the loop of the eyebolt, and the parts then, by means of the nut and the eyebolt, re

clamped and interlocked as before.

It will be seen that by myinvention a scythesnathfastening is provided which, by reason of the employment of the sliding socket-piece formed with teeth and the slotted face-plate, also formed with teeth, I am enabled solely by the use of the usual eyebolt, O, and nut c to provide a simple, cheap, and efficient contrivance by which the clamping and adjust ments of the scythe maybe readily and speedily accomplished.

Of course modifications in details may be made without departing from the spirit of my inventionfor instance, instead of making the slot F curved, it may be made straight, and in lieu of radiating it may have straight, parallel, or other serrations, in which case the shoe piece should be serrated to correspond.

What I claim as new, and desire to secure by Letters Patent, is p l. The combinatiom with the snath and the usual ferrule, eyebolt, and nut, of the slotted and toothed face-plate, substantially such as specified, and the toothed sliding socket or shoe piece E, that is provided with a hole for the accommodation of the claw of the scythetang, the whole constructed and operating substantially as and for the purposes hereinbefore set forth.

2. The combination, with the snath and the usual ferrule, eyebolt, and nut, of the slotted toothed faceplate and the toothed sliding socket or shoe piece E, that is formed or provided with means for retaining it in connection with the said face-plate, all substantially in the manner hereinbefore set forth.

In witness whereof I hereunto set my hand this 21st day of April, 1885.

JOHN sIMPsoN.
